DOOR-LATCH.

Specification of Letters Patent.

Application filed May 1, 1918'. Serial No. 231,882.

To all whom it may concern:

Be it known that 1, WILLIAM M. KATZ- BERG, a citizen of the United States, residing at Hastings, in the county of Adams and State of Nebraska, have invented certain new and useful Improvements in Door- Latches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in door latches.

An important object of my invention is to provide a device of the character described, which may be applied to any door in a highly convenient and expeditious manner.

A further object of the invention is to provide a latch adapted for attachment to a door and which may be operated from either side of the door with equal convenience.

A further object of the invention is to provide a device of the character described which is neat in appearance, few in parts and cheap to manufacture.

A further object of the invention is to provide a latch for attachment to doors, which by virtue of its extreme simplicity in construction and cheapness of manufacture, will successfully compete with numerous other similar devices in a highly crowded art.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a front elevation of my improved door latch applied to a door,

Fig. 2 is an elevation of one handle of the lock extended through the door shown in Fig. 1,

Fig. 3 is a section taken along line 3-3 of Fig. 1,

Fig. is a section taken along line l4 of Fig. l,

Fig. 5 is a front elevation of the spring means for holding the latch in a normally closed position,

Fig. 6 is a perspective of the controlling handle for the latch,

7 is a section taken on line 7-7 of Fig. 1, and,

Fig. 8 is a section taken along line 88,

showing means for engaging one handle of the latch when the door is open.

In thev drawings, wherein'for the purpose of illustration, is shown the preferred em bodiment of my invention, the numeral 10 deslgna'tes a door mounted on hinges 11. A metallic strike or keeper 12 is secured to a door frame 13 by screws 14 or other suitable means and this strike 12 is bent outwardly as shown at 15 and is provided with an opening 16.

The door 10 is provided with an elongated opening 17 for the reception of a metallic rod 18 passing therethrough. One end of the metallic rod 18 is bent to form a rectangular loop 19. A metallic plate 20 is secured to one side of the door by screws 21 or other means and is provided with a longitudinal slot 22 for the. reception of the inner portion of the rectangular loop 19. This plate 20 serves as a hinge or pivot for the metallic rod 18. As clearly shown in Fig. 3, the rod 18 extends through the door 10 and is provided with a semi-circular curve 23 on a horizontal plane with the rectangular loop 19. Carried by the end of the semi-circular curved portion 23 is a striker head 24 adapted toengage the strike 12 when the door is closed. The semi-circular curved portion serves as a handle for swinging the striker element 24 into engagement with the strike 12, while on the opposite side of the door the rectangular loop serves as a means for operating the latch.

As clearly shown in Fig. 5, a spring 25 is provided to normally hold the striker element 24: in engagement With the strike 12. One end of this spring 25 is apertured as at 26 to receive a screw for attaching this end of the spring to the door while the opposite end is curved as shown at 27 for extending over the top of the metallic rod 18. To prevent a lateral movement of the spring 25, an apertured plate 28 is provided on the outer side of the spring and is secured 'to the door as shown.

As shown in Figs. 1 and 8, a second strike is provided adjacent the door 10 and on a horizontal plane with the latch, the same being adapted to engage the semi-circular end portion 23 when the door is open.

It is apparent that in the use of my device, the latch may be operated by either an upward or a downward movement of the members 23and 19 as the case may be.

While I have shown and described the preferred embodiment of my invention, it is understood that I may make such minor changes in arrangement and construction of parts, as Will remain Within the spirit of the invention and the attached claims.

Having thus described my invention, What I claim is:

l. A door latch including a rod extending through a door and having one end portion bent to provide a rectangular looped handle and having its opposite end portion arranged on the opposite side of the door and curved longitudinally to provide a combined handle and locking member, a plate secured to one side of the door and receiving the inner portion of said rectangular loop, and

a keeper, adapted to be engaged by said combined handle and locking member.

2. The construction set forth in claim 1,

a second plate arranged on the opposite side a of the door from said first named groove and having an opening receiving said rod, the central portion of said second named plate being spaced from the door, and a spring extending between said door and said second named plate.

In testimony whereof I affix my signature in presence of tWo Witnesses l/VILLIAM M. KATZBERG. Witnesses:
